As Project Manager at cosine, you turn ambitious space instrumentation programs into successful reality.
Working within our Remote Sensing business, you lead multidisciplinary development projects that bring advanced space borne
optical instruments from concept to launch. These instruments play a key role in planetary science, environmental protection,
security and defence, empowering scientists and organisations worldwide to deepen their understanding of Earth and the universe
beyond.
You create structure in a highly innovative environment, balancing technical excellence with planning, budget, quality, and
stakeholder expectations. The projects you manage typically have budgets of up to €20 million and directly contribute to missions
with impact far beyond Earth.
